IMPROVEMENT IN BRAKES FOR COTTON-LAPPERS.

Specification forming part of Letters Patent No. 58,915, dated October 1G, 1566.

To all whom it may concern.

Be it known that I, DANIEL lIUssnv, of Nashua, in the county of IIillshorough and State of New Hampshire, have invented a new and useful Improvement in Brakes for Cotton-Lappers, of which the following is a full, clear, and exact description, reference being' had to the accompanying drawings, making part ot'this specitication, in which- Figure 1 is a rear-side elevation of a cottonlapper having my improvement applied thereto. Fig. 2 is an end view after a portion of the frame has been removed, and Fig. 3 the opposite end. Fig. -I is a central longitudinal section of a detached arm and gear; Fig. 5, a side view ot' a detached lever, friction-weight, and the rim of a friction-pulley; Fig. 6, a side View of a detached ratchet-wheel, having a pinion-gear connected therewith, anda transverse section ot' a top girt, N, with a regulating spring, R, fastened to the inside of the girt, all ot which pertain tothe said invention.

In the drawings, A is a ratchet-wheel, fitting loosely on the shaft B, and a bevel-gear, (I, is fastened to the inner side of said ratchet. A spur-gear, D, lits loosely on the shaft B, and a bevel-gear, U2, like the first, is fastened to the inner side of the gear l). An arm, E, tits on the shaft B between the bevel-gears, and is held iirinly to the shaft by a set-screw or other suitable device. A bevel-pinion gear, F, rotates on the outer end of the arm Il, and engages with both ofthe bevel-gears U and G2. The ratchet-wheel A is held up against the hub ofthe arm E by a collar, b, titted on the shaft B. A lever, G, fits loose!)` on the shaft B, the hub o of which comes against the outside of the gear D. A collar, c, on the shaft B holds the lever Gr up against the outside of the gearD, and also holds the latter up against the hub of the arm E.

A ratchet-wheel, II, having a friction-pulley, I, on one side, turns freely on a stud, d, projecting from one side of the lever G, and a pinion-gear, J, on the opposite side of the ratchet-wheel H, gears into the larger gear D.

A vertical arm, K, rises from the top edge of the lever G, and an adjustable frictionweight, L, is hung to the arm K, near its top end. This friction-weight rests on the top of the friction-pulley I, and a spring or other device may he applied to the top of the frictionweight to increase the friction on the pulley I.

An arm, l, projects from the outer end of the lever G, and the lower end of aconnecting-rod, m, connects with the outer end of said arm. The top end of this rod connects with the end ot' a cross-lever, M, which swings on a fulcrum, n, projecting outward from the top girt N 0f the machine.

A weight or a spring, P, acts upon the long end lt) ofthe lever M and holds the lever (l and its connections up in their place. A regnlating-spring, It, is fastened to the inside of the girt N, and the lower end ot said spring engages with the teeth of the ratchet-wheel II.

I einplov the usual calenderrolls S and the pressure-roll T, which rotates in bearings near the top of the vertical sliding-racks lV. These racks act upon pinions c on each end of the shaft B, as usual. I also employ a foot-lever, W, having a counterbalanee-weight, y, on one end to bring it into contact with the teeth of' the ratchet A. Said lever swings on a pin, e, passing through earsjot' a stand on the top ot' the cross-girt g.

Motion is given to the calender-rolls S by a drivin g-gear, which en gages with a gearor gears 0n said rolls, and when the cotton-lappers having my im provenientthereto applied are in operation the ratchet-wheel A and gear C are prevented from turning by the tooth hon thefoot-lever W', held in contact with a tooth on the ratchet-wheel A. The lap of cotton is formed on a smallroll between the calender-rolls S and the pressure-roll T, and as the lap is increased in diameter the roll T and vertical racks W are drawn upward. Said racks, acting on the pinions c, impart a very slow, strong, and steady rotary motion to the shaft B, the arm E, and pinion F. The latter, acting against the gear G on the ratchet-wheel A, and at the opposite side upon the gear C2, secured to the gear I), causes the gear I) to rotate in the same direction. rThe gear I) engages with the pi11ion-gearJ on one side ot' the ratchet-Wlel H, and turns the pinion J, the ratchet-Wheel H, and friction-pulley I in the opposite direction.

The faction-weight L, resting'on the rim of the pulley I, or being pressed against the surface of said pulley-rim, prevents any sudden or rapid rotation of the atehet-wheel ll when the machine is in motion.

The lower end ofthe spring teenies in een tact` with the teeth ot' the ratehet-wheel 1I, and serves, in connection with the frictionweight L, to regulate the motion or velocity of said wheel, letting' ott' one tooth ati a time as the diameter ot' the roll increases, thereby preserving` a. unit'orin tension and pressure on the lap while forming, keepingv the same even throughout and at all times.

And as the material of which my improved friction deviee is made (it being,r ofniet-al) preeludes the possibility ot' its being,` aii'eeted by damp or duY atmosphere, no change in the weather can have any ell'ect to prevent the certain and harmonious aetion oi' the same, and need not be changed in consequence of atmospheric Changes, as is nsuallbv the ease in most other cotton-lappers.

Any slight` change in the weather makes the leather more or less adhesive, thereby inereas ing' or diminishingthe t'rietion and making the lap very uneven, or breakingr or tearing asunder said lap between the delivery-rolls and the ealenderrolls, or ou the partly-termed lap. Besides, the friction eaused by the expansion ofthis leather is so great attimes that the gears ot' the machine will break before the leather ean vield and allow the shaft to turn.

What I elaim as of myinvention,aml desire to secure by Letters I'atent, in lap-winding machines, is

1. The emphwnient ot' the arm E and piniongear Il, in eombination with the bevel-gears (l and UZ and ratehet-wheel A, all arranged to operate substantially in the manner and t'or the purpose set` l'orth.

2. The gear I) on the shaft B, in eombination with the bevel-gears (l and U2, pinion F, and arm E, when the said gear engages with the pinion J to operate said pinion and its connections, substantiall)v in the manner and for the purpose set forth.

rlhe ratchet-wheel ll', or its equivalent, in Combination with the friction-pulley I and frietion-weight L, arranged and made to operate substantially in the manner7 by the means, and for the purpose set forth.

4. The lever Ur on the shaft B, when they said lever is formed, arranged, and combined with the pulleyY I, ratchet-wheel II, and friction-weight L, substantially as and for the purpose speeitied.

5. rlhe connecting-rod m, or the equivalent thereof', in combination with the arln I, cross lever M, and a weight or spring, l?, all arranged to operate substantially as and t'or the purpose specified.

t. The spring; l, in combination with the ratehet-wheel Il, pulley l, and 'rietion-weight L, and arranged to operate substantially` in the manner and for the purpose explained.

'i'. The combination of the ratchet-wheel A, bevelgear C, arm lil, pinion 1V, bevel-gear C2, spul-gear l), lever (l, with arms l( and I, ratchet-wheel Il, or equivalent, the pinion J, trietion-pulleyl I, friction-weight L, eonnectingrod m, lever M, and weight or springl, with the shaft 13, the whole arranged to operate substantiallr as and l'or the purpose set` tortih.
